J/P dimension is primary?

[consentingadult]

I'd like a good description of what is rational behavior and what is irrational.

Is this a good one?

Cause by these standards, rationality fits me better.

Or are we going to go by shit like "J types are tidy and P types are messy"?

Rick's work is exactly what got me thinking about this issue. Sometimes I think his work is a bit too abstract, but more than other sites I've seen, he seems to be on the right track.
